【摘要】 利用二维流体模拟方法研究等离子体显示屏(PDP)大维持电极间隙单元之间的放电串扰现象.研究发现当维持电极间隙较大时,无论它们之间是否有浮动电极,均可能发生相邻单元之间的放电串扰;同时,串扰还与工作电压有关,电压越高越容易发生串扰.模拟结果显示,串扰仅发生在最初几个维持放电脉冲期间.在单元之间插入浮动电极,可以有效地阻止单元之间的放电串扰而不影响Xe 放电激发效率.更多还原

【Abstract】 The discharge cross-talk between neighboring cells of PDP with long gap between twosustaining electrodes has been studied by using two dimensional fluid model.In the configuration oflarge sustaining electrode gap,the cross-talk would occur whether there exists a floating electrodebetween two sustaining electrodes or not.Meanwhile the cross-talk depends on the operation voltage.The higher the voltage,the easier the cross-talk takes place.But the cross-talk only occurs during firstseveral earlier sustaining pulses in simulations.Inserting a floating electrode between neighboring cellswould help to prevent the cross-talk effectively while keeping the efficiency of Xe excitationunchanged.更多还原
